' Letters Patent No. 111,753, dated February 14, 1871.

The Schedule referred to in LettersPatent and making part of the same.

To all whom it may concern Be it known that I, P1111111 KLQTZ, ofBaltimore, in the county of Baltimore, and State of Maryland, haveinvented certain Improvements in Fire-Place Stoves; and I declare thefollowing to be a full, clear, and exact description thereof, referencebeing bad to the accompanying drawing, in which-- Figure 1 is a frontelevation, and

Figure 2, a vertical section on line a: a: of fig. 1.

Similar letters of reference indicate like parts.

In the drawiug D represents the top section -of the stove provided witha door, a, which has a flange or cut-ofi', a, applied upon its innerside, and operating, in combination with the space between the wall ofthe section and the ,wall of the magazine extension G, in such a mannerthat when said door is shut the interior of the mag,

zine will not be influenced by the draught of the stove, but when thesaid door is open the draught of the store will prevent the escape ofthe gas from the magazine into the room, substantially asdescribed in myformer patent.

I now apply to the door a an air-register, r, of any approvedconstruction and design, whereby a draught of air can be admittedthrough the closed door into the extension G, and thence down throughthe magazine G to the fire-pot R,.'to support combustion.

It is obvious that when this draught is open the upward draught from thebase of the stove may be shut off, partially or entirely, and by aproper adj ustment of the two draughts the intensity of combustion inthe fire-chamber may be held under the most complete control.

By the downward draught through the magazine the walls of the latter,together with the unconsumed coal within it, are prevented from becomingimproperly heated, and combustion is limited to the space immediatelyaround the lower end of the magazine.

With the downward draught properly adjusted, a single magazine full ofcoal in a fire-place stove has been known to burn continuously for twoor three days, and when burning with ordinary intensity the fire willheat the coal in the upper part of the magazine so slightly that it maybe removed by hand without inconvenience.

It is evident that by thus confining the heat to its appropriate chamberthe upperworks of the stove are prevented from premature destruction,and-the fuel is econom'ized. to the utmost possible extent.

This invention, although designed particularly for fire-place stoves,maybe applied to other stoves the construction of which issueh' as tomake-its application desirable. r

Having thus described my invention, 4 I

What I claim as new, and desire to secure by Letters Patent, is

1. In connection with a base-burning magazine,

G G, the sides and top of which are air-tight. when the feed-door isclosed, an air-register, 1:, arranged to open directly into the.magazine above the coal con tained therein, siibstantially as and forthe purposes- 2. The combination of the air-registers with the door tohaving the flange a, the magazine G G, and the space around the upperend of the extension G, substantially as described, and for the purposesset forth.
